fl 0 all whom iii-may concern:

Be it known that I, ABRAHAM ROSENBERG,

a citizen of the United States, residing in Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Exercisers, of which the following is a specification.

This invention relates to improvements in as to provide amusement andpleasure with out danger.

which, when in use, does not interfere with, or damage, articles offurniture or the surroundings, including the floor or carpets on whichit rests, the device being safe when used by a strenuous child, as itwill not overturn and while having the functions of a rocker, is initself rockerless, means also being provided whereby its equilibrium isnormally maintained.

Its use as an exerciser is found valuable in gymnasiums and hospitals inthe cure of invalids suffering from back-sprain, etc, and is highlybeneficial to anemics when operated in the open air.

These and other like objects are attained by the novel construction andcombination of parts hereinafter described and shown in the accompanyingdrawing, forming a material part of this disclosure, and in which Figure1 is a perspective view, showing an exerciser made in accordance withthe invention, and

Fig. 2 is a vertical sectional view, taken substantially through thecenter of the same.

In carrying out the invention, use is made of a platform 10, havingarcuate ends 11, the side elements being rigidly connected by cross bars12. Secured to lower surface of the platform are contact elements 14,preferably made of rubber or like pliable material, so as to avoiddamage to the carpet or floor upon which the apparatus may rest.

Rising from the center of the side elements of the platform are uprightstandards 15, containing openings, here shown to be arcuate slots 17, inwhich are mounted spindles 18, extending from flanges 19, which aresecured upon the opposite sides 20, of a movableelement which may takeany preferred form, as that of a hobby-horse, sled, car or carriage,provided with a flooring 21, a seat 22, in connection with the back rest23, and a foot or dash board 24, at the front, the car being an adequatesize to contain one or more persons as may be desired.

. Attached to the back-rest 23 and the foot board 2 1, respectively, bybrackets 26, are open hooks 27, in which are engaged the ends ofhelically wound tension springs 28, the opposite ends of which areengaged with similar hooks 29, secured to brackets 30, fixed upon thefront and rear elements of the platform at spaced distances apart, ascan best be seen in Fig. 2, and it is to be noticed that the springs areso engaged with the Another object is to provide a device hooks thatthey maybe readily removed therefrom, while the car itself may bemaneuvered so that the extending spindles 18, may be withdrawn from theslots 17, permitting the structure to be readily dismounted. The shapeof the slots is obviously such that the car will, by gravity, assumenormally a central position with reference to the supporting standards.

It is to be understood thatthe word car is to be construed as embracingany suitable element upon which a person may rest and actuate thestructure.

In operation, a person sitting upon the seat may, by movement of thebody or the limbs, cause the car to oscillate something in the manner ofa rocker, this movement being materially augmented by reason of thesprings, while a slight to and fro movement is attained, due to theslots in the standards, thereby giving a pleasurable and exhileratingsensation to the rider, calling into action the muscles of the back in abeneficial manner, tending materially to strengthen and improve thesame.

While I have shown and described a working embodiment of the exerciser,I do not desire to be held strictly to the exact construction set forth,as manifestly the same may be very considerably modified withoutdeparting from the spirit of the invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is.

1. In an exerciser the combination with a platform having cushionedcontacts adapted to rest upon a substantially level surface, of a pairof standards arranged centrally on the sides of said platform, spindlesrotatably mounted in said standards, means permitting said spindles .tomove limitedly to and fro in their bearings, a car supported by said Ispindles, and a plurality of springs attached.

at one end to the front and rear of said car, and to the front and rearof said platform at their other ends whereby said car is resilientlyheld in a normally central position.

2. In an exerciser, the combination with a platform having cushionedfeet secured upon its lower surface and adapted to rest upon asubstantially level surface, of a pair of standards rising from thesides of said platform, arcu-ate' slots formed at the upper end ABRAHAMROSENBERG.
